Two piles of heavy boxes must be lifted onto a shelf. Each pile has 20 boxes and each box is the same size and weight. Tom and claudia are each responsible for a pile. Tom lifts each box straight up from the pile to the shelf. Claudia places a long gradual ramp that leads from pile to the shelf. She pushes each box up the ramp until it rests on the shelf.

Tom used more Force but over a shorter distance. Tom and Claudia both did the same amount of work.

In this scenario, we can tell that Tom used more force.


We can tell this is correct because Tom did not use any shortcuts like Claudia did. Claudia placed her heavy box on a ramp that then transferred her box to where the shelves are. After that, all she had to is put the box on the shelf.
